Gravel Road Suspension Recommendations

I have a 2012 DCSB TRD off road that currently has a 3" Toytec spacer lift in the front and 1.5" AAL in the rear. I knew the toytec lift would preload my suspension and make the ride stiff, but it was a cheap way to get my truck lifted and I figured that since I spend 90% of my time on the road it wouldn't matter.

Now I don't do any hardcore wheeling with my truck, but the offroading that I do is all driving up gravel logging roads (forest service roads). Keep in mind I can only drive about 15-30mph on these roads because I live in WA and we have lots of sharp corners

After lots of research on here, I've come to realize that I need more down travel in my suspension and less preload. The only way I can see to get it is to lower my truck down to to around 1.5"-1.75" of lift or get some extended travel coilovers like the Icons with new upper control arms. This would be fine, but I'm running 285/65r18 tires and I doubt they will clear without at least 2.5" of lift.

So what are my options for a suspension that will ride well over potholes and washboard at around 15-30mph? I've heard the Icons work best at higher speeds (50+ mph???).
Will upper control arms make a difference with the suspension I have now? I don't think it will because the strut is probably already near the max of it's extension.

 

Icons for that my friend.....in terrain like that high speed is anything over 15-20mph really. 50+ is LT status and the rest of the truck couldn't handle those speeds even if the coilovers could.

I had a spacer lift, then Toytec ULT, then upgraded to Icons as 15mph was as fast as I could go on pitted, pot holed and washed out roads (even with the toytecs). The Icons get smoother the faster you go too.
